Lena-g Patent No. 102,277, dated April 2c, 1870.

IMPROVEMENT IN WOODEN PAVEMENT.

The Schedulereferxed to in these Letters Patent and making part of the same.

To all whom it may concern v Be it known that I, S'rnIcxLAND KNEAss, of the cit-y of Philadelphia and State of Pennsylvania, have invented a new andv iinprdved form and arrangement of wooden blocks and bearing-strips as applicable to the formation of 'Wooden Pavements for streets, roads, and highways andI do hereby declare the following to be a full, clear, and exact description thereof', reference V being had to the accompanying drawing and the-letters of reference-thereon, and vwhich represents in perspective a portion of a pavement laid after my plan.

v I am aware that keys and bonds have been used in many forms, both wood and metal, for holding together a sexies of b1ocks. n YIdo not claim a key or bond of any kind as such,

' `and`.n1ention them simplythat my bearing-strips may not be confounded with'keys' or bonds, which, as a general thing, are so arranged that they must rise with the blocks being fastened to or passing through recesses of some kind in the blocks.

Myinvention consists in providing ordinary rectangular blocks of wood with an upper and alower rebate .upon both of their longitudinalsides, so proportioned as to allow the blocks when in place to be in close juxtaposition one with the other, and at the same` Ihe blocks may be of any convenient size as to length, height, and width.

Upon each side of the upper ends of the blocks are formed rebates B B, and upon the lower ends thereof other rebates C (l, thus leaving the blocks as at D, of fullsize, so that at thesepoints they will'be in close juxtaposition when laid.

.'l lso prepare bearing-strips E,-of good tough wood, or of scantling, and of' such size as to lit snugly'inA the space formed by the two lower rebates O, and of such lengths as may be found most desirableL The blocks, prepareda's above described, are then set on end in lines across the roadway, and the bearingstrips are then introduced into the rebates, or the bearing-strip may be introduced into the half` rebate, and the next rowof blocks laid up against'it. When' a section of the roadway i's so laid tbe concrete may be poured and rammed intothe npperrebate,"the surface slushed with coal-tarand sanded, andthe road is nished ready for use.

For the sake of perinenancy and endurance, each block and strip is dipped into ordinary bituminous or other preserving compound before set in place.

Having thusA fully described my invention,

In combination with a series of blocks A that abut against each other ornearly so, and have rebates above and below such adjacent parts, a series of bearing-strips E in the lower rebates, and concrete in the upper rebates, for the purpose of forming a wooden pavement on a previously-prepared foundation, as herein described and represented.

STRICKLAND KNEASS.
